Knowledge of factors that influence oviposition behavior of malaria mosquitoes is critical to vector control measures aimed at larval habitat modifications and source reduction. Anopheles minimus s.l., an important malaria vector in Southeast Asia, generally breeds in clear, unpolluted water along shaded grassy edges of slow-moving streams. The objective of this study was to determine the influ...

BACKGROUND AND AIMS The low-temperature range limit of tree species may be determined by their ability to produce and disperse viable seeds. Biological processes such as flowering, pollen transfer, pollen tube growth, fertilization, embryogenesis and seed maturation are expected to be affected by cold temperatures. The aim of this study was to assess the quality of seeds of nine broad-leaved tr...

We investigated community structure and tree species diversity of six subtropical mountain forests in relation to 11 topographical and edaphic factors in Lower Lancang River Basin, Yunnan Province, China, based on a census of all trees with diameter at breast height≥5 cm in 45 0.06-ha plots. The forests were as follows: a river valley monsoon forest, semi-humid evergreen broad-leaved forest, mo...

This review will first cover the researches done in determining KNOX family gene functions and mechanisms. Followed by phylogenetically, how KNOX family proteins expressed differently in different species functioned differently, and the differences between single leaved and compound leaved species. Onto the significance of different expression pattern of KNOX genes in developing tomato compound...

BACKGROUND AND AIMS Seagrasses are important facilitator species in shallow, soft-bottom marine environments worldwide and, in many places, are threatened by coastal development and eutrophication. One narrow-leaved species (Zostera marina) and one wide-leaved species, variously designated as Z. marina, Z. pacifica or Z. asiatica, are found off the California Channel Islands and adjacent Califo...

Divergence times and biogeographical analyses have been conducted within the Loliinae, one of the largest subtribes of temperate grasses. New sequence data from representatives of the almost unexplored New World, New Zealand, and Eastern Asian centres were added to those of the panMediterranean region and used to reconstruct the phylogeny of the group and to calculate the times of lineage-split...

Neglecting tree size and stand structure dynamics might bias the interpretation of the diversity-productivity relationship in forests. Here we show evidence that complementarity is contingent on tree size across large-scale climatic gradients in Europe. We compiled growth data of the 14 most dominant tree species in 32,628 permanent plots covering boreal, temperate and Mediterranean forest biom...

Leaf size varies by over a 100,000-fold among species worldwide. Although 19th-century plant geographers noted that the wet tropics harbor plants with exceptionally large leaves, the latitudinal gradient of leaf size has not been well quantified nor the key climatic drivers convincingly identified. Here, we characterize worldwide patterns in leaf size. Large-leaved species predominate in wet, h...

An important problem in phylogenetics is the construction of phylogenetic trees. One way to approach this problem, known as the supertree method, involves inferring a phylogenetic tree with leaves consisting of a set $X$ of species from a collection of trees, each having leaf-set some subset of $X$. In the 1980's characterizations, certain inference rules were given for when a collection of 4-l...

The objectives of this study were to identify the antioxidants in acid hydrolysates of six of Taiwan’s indigenous purple-leaved vegetables (IPLV), including purple-leaved sweet potato (Ipomoea batatas L. Lamark), purple-leaved gynura line 1 (Gynura bicolor D.C.), purple-leaved gynura line 2 (Gynura bicolor D.C.), purple-leaved perilla line 1 (Perilla frutescents L. Britton), bicolored-leaved pe...
